2 Claims.

inventionrelates to closures for receptacles of flexible material, suchas leather, fabric, etc.,

and it is an improvement over my Patent $72 ,255,598, of September .9,1941, filed September 7, 1939.

The improvement has reference to the type of closure providing a rigidframe member forming one side of the aperture and serving as an abutmentfor a movable-framemember, formed of telescoping sections-with means formaintaining the movable frame member firm in either open or closedposition by the inherent resilient resistance to. deformation of one ofthe telescopingime'mbfers; the movable frame member forming'the'other"sid'e of the aperture when moved away from the rigid member.

An object of the invention is to provide a closure that will facilitateaccess into the receptacle through the aperture thereofv when open.

Another object of the invention is to provide a closure which will bringthe upper edge of the movable frame member to lie in a plane differentfrom that of the upper face of the rigid frame member when the apertureof the closure is open.

In the appended drawing forming part of this application:

Figure 1 is a fragmentary plan View of an end of a closure embodying oneform of my invention.

Figure 2 is a section on line 2-2, Figure 1, showing the position of thetelescoping members in reverse order from that shown in Figure 1.

Figure 3 is a plan view of a different form of my closure, and

Figure 4 is a section on line 4-4, Figure 3, showing the position of thetelescoping members in reverse order from that shown in Figure 3.

In the description and. claims, the term rigid member includes eithersolid or tubular forms and of a triangular or trapezoidal cross section;the sloping side or face, whether one or two, of the rigid member thatforms part of the contour of the aperture of the closure issymmetrically disposed with reference to the median longitudinal planeof the rigid member.

Referring to the drawing:

5 is a rigid member extending through the length of the aperture forwhich the closure is intended and, as shown in Figures 1 and 2, is oftriangular cross section, the side 6 thereof forming the upper face ofthe closure while the opposite ridge 1 forms the bottom.

The lateral sides 8 of the rigid member 5 are (Cl.f15010i) 2 slopinginwardly with reference to a container that it is toacconrnnodate.

Pivotally mountedon eachsloping side S 'near the ends of the rigid'framemember 5 are hinges 9, the pivotal axes of said hinges 9 on the samesloping side are in 'a common plane parallel to the side 8 andi'n"which-plane the axes of the hinges are parallel to each other. Thetwo hinges on the sameside areconnected to a mov'-' able frame membe-"comprising a spring section II), which is mounte'dflto telescope-inend sections H, each of which'h'a's one end connected to the adjacenthinge: The inherent resiliency of the spring section f0-tends to retainthe shape itassumes whensheathed insections H or when extending out ofsaid-sections- H;

As seen in Figure 2, one of the movable frame members is shown abuttingthe adjacent sloping side 8, while the other movable frame member isshown in an exaggerated open position, that is to say, moved away fromthe adjacent sloping side 8, and. when in the open position, the upperedge of the movable frame member will lie in a plane substantiallyperpendicular to the slope of the side to which it is attached. Inconsequence, a major part of the upper edge of the movable frame memberwill lie below the level of the top of the rigid member 5, with thecentral part thereof the lowest and the extremities thereofsubstantially at the level of the top, though in a different plane fromthat of the top.

Due to this relative position of the rigid and movable frame members,the aperture formed between them eases the accessibility into thereceptacle through the closure.

In cases where the receptacle is large, a partition l2 may be providedthrough the length of the rigid frame member as indicated in Figure 2.

In Figures 3 and 4, the rigid member 5' is shown also triangular incross section, except that the side 6 forms the bottom of the closurewhile the ridge I is at the top. The sloping sides 8', therefore, at theopening will slope outward, so that when a movable frame member, formedby telescoping sections I0 and II, is moved from the abutting position,as shown on the right side of Figure 4 to that shown on the left sidethereof, it will bring the major portion of the upper edge of themovable frame member above the ridge 1' of the rigid frame member, thusfa-' cilitating the access to the receptacle through the closure.

The tendency of the spring section III or ID in the movable frame memberis to offer resistance to deformation, due to the inherent resilientresistance to deformation when it is pulled to open or due to thefrictional resistance of the various elements when it is pushed to closethe opening between the rigid and movable frame members.

By forming a sloping side as part of the aperture of the closure fromwhich the telescoping sections of the moving frame member swing out, sothat the major upper portion of the edge is either above or below theupper face of the rigid frame member, as shown in Figures 1 and 2 or asshown in Figures 3 and 4 respectively. In either case the telescopingmembers form an acute angle with the longitudinal median plane of theframe 5 or 5' extending from the base 6 or 6' of the frame memberbetween the sloping sides 8 or 8 of said frame member.. construction Iobtained a better accessibility By this 2. A closure for receptaclescomprising a rigid frame member of triangular cross section, one side ofwhich is perpendicular to the median plane of the triangular member,each of the other two sides of which forming part of the aperture of theclosure, and said two sides being symmetrical to said median plane andsloping with reference thereto, anda movable frame member on eachsloping side and pivotally connected thereto at the ends of the rigidframe member, said movable frame members being formed of telescopingsections arranged to maintain said movable frame member firmly in eitherabutting position or when moved away from the rigid frame member, eachof said movable members when being moved from the sloping side to whichit is connected lies in a plane substantially perpendicular to thesloping side but at an acute through the aperture to the containerprovided with such a closure as described. .lclaim:
